Jetboil Jetpower Fuel – 230 g

The 230 g JetPower canister is Jetboil's mid-size fuel option, carrying the same four-season isobutane-propane blend as the smaller 100 g version but with more than double the fuel for trips running beyond a few days. Its Lindal EN417 valve is compatible with the full Jetboil stove lineup — Flash, MiniMo, MicroMo, Stash, SUMO, Zip and others — as well as any other stove built around the same standard valve, so it is not locked to a single brand's burners. The propane fraction in the isobutane-propane mix is what matters most in cold conditions, since propane maintains usable vapour pressure at lower temperatures than isobutane alone, keeping burn performance more consistent as the canister empties and internal pressure drops. At 230 g of fuel, it sits between the 100 g canister suited to short trips and the 450 g size aimed at longer expeditions or group cooking, making it a reasonable middle ground for week-long solo or duo trips without carrying more fuel than needed.
